What are the best practices for using static methods in programming?

Static methods are useful for utility functions, but here are some best practices to consider: 1. Keep them stateless. 2. Use them for operations that don't require object state. 3. Avoid overusing them to maintain flexibility in your code.

Can you explain why keeping them stateless is important?

Keeping static methods stateless ensures that they don't depend on or modify the state of an object, making them easier to test and reuse.

What are some examples of when to use static methods?

You can use static methods for utility functions like mathematical calculations, string manipulations, or factory methods that create instances of a class.

Are there any downsides to using static methods?

Yes, overusing static methods can lead to code that is harder to test and maintain, as they can introduce tight coupling and reduce flexibility.
